1 Summary 2 ======= 3 4 This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1] 5 and Cortex-A9/A53/A57 based R-Car[2] family of SoCs. Renesas's RMOBILE/R-Car SoC 6 family contains an ARM Cortex-A9/A53/A57. 7 8 Currently the following boards are supported: 9 10 * KMC KZM-A9-GT [3] 11 * Atmark-Techno Armadillo-800-EVA [4] 12 * Renesas Electronics Lager 13 * Renesas Electronics Koelsch 14 * Renesas Electronics Salvator-X M3 15 * Renesas Electronics Salvator-XS H3 ES2.0+ 16 * Renesas Electronics ULCB M3 / H3 ES2.0+ 17 18 Toolchain 19 ========= 20 21 Either ARMv7 toolchain for 32bit Cortex-A9 systems or ARMv8 (aarch64) 22 toolchain for 64bit Cortex-A53/A57 systems. Currently we compile the 23 32bit systems with -march=armv5 to allow more compilers to work. (For 24 U-Boot code this has no performance impact.) 25 26 Currently, ELDK[5], Linaro[6], CodeSourcery[7] and Emdebian[8] supports 27 ARMv7. Modern distributions also contain ARMv7 and ARMv8 crosstoolchains 28 in their package feeds. 29 30 Build 31 ===== 32 33 * KZM-A9-GT 34 35 make kzm9g_config 36 make 37 38 * Armadillo-800-EVA 39 40 make armadillo-800eva_config 41 make 42 43 Note: Armadillo-800-EVA's U-Boot supports booting from SDcard only. 44 Please see "B.2 Appendix B Boot Specifications" in hardware manual. 45 46 * Lager 47 48 make lager_config 49 make 50 51 * Koelsch 52 53 make koelsch_config 54 make 55 56 * Salvator-X M3 57 58 make r8a7796_salvator-x_defconfig 59 make 60 61 * Salvator-XS H3 ES2.0 62 63 make r8a7795_salvator-x_defconfig 64 make 65 66 * ULCB M3 67 68 make r8a7796_ulcb_defconfig 69 make 70 71 * ULCB H3 ES2.0 72 73 make r8a7795_ulcb_defconfig 74 make 75 76 Links 77 ===== 78 79 [1] Renesas RMOBILE: 80 81 http://am.renesas.com/products/soc/assp/mobile/r_mobile/index.jsp 82 83 [2] Renesas R-Car: 84 85 http://am.renesas.com/products/soc/assp/automotive/index.jsp 86 87 [3] KZM-A9-GT 88 89 http://www.kmckk.co.jp/kzma9-gt/index.html 90 91 [4] Armadillo-800-EVA 92 93 http://armadillo.atmark-techno.com/armadillo-800-EVA 94 95 [5] ELDK 96 97 http://www.denx.de/wiki/view/ELDK-5/WebHome#Section_1.6. 98 99 [6] Linaro 100 101 http://www.linaro.org/downloads/ 102 103 [7] CodeSourcey 104 105 http://www.mentor.com/embedded-software/codesourcery 106 107 [8] Emdebian 108 109 http://www.emdebian.org/crosstools.html 110
